1 Introduction

OpenRCT2 is an open-source re-implementation of RollerCoaster Tycoon 2 (RCT2). The gameplay revolves around building and maintaining an amusement park containing attractions, shops and facilities. The player must try to make a profit and maintain a good park reputation whilst keeping the guests happy. OpenRCT2 allows for both scenario and sandbox play. Scenarios require the player to complete a certain objective in a set time limit whilst sandbox allows the player to build a more flexible park with optionally no restrictions or finance.

RollerCoaster Tycoon 2 was originally written by Chris Sawyer in x86 assembly and is the sequel to RollerCoaster Tycoon. The engine was based on Transport Tycoon, an older game which also has an equivalent open-source project, OpenTTD. OpenRCT2 attempts to provide everything from RCT2 as well as many improvements and additional features, some of these include support for modern platforms, an improved interface, improved guest and staff AI, more editing tools, increased limits, and cooperative multiplayer. It also re-introduces mechanics from RollerCoaster Tycoon that were not present in RollerCoaster Tycoon 2. Some of those include; mountain tool in-game, the "have fun" objective, launched coasters (not passing-through the station) and several buttons on the toolbar.

2 Downloading the game (pre-built)

OpenRCT2 requires original files of RollerCoaster Tycoon 2 to play. It can be bought at either Steam or GOG.com. If you have the original RollerCoaster Tycoon and its expansion packs, you can point OpenRCT2 to these in order to play the original scenarios.

OpenRCT2.org offers precompiled builds and installers of the latest master and the develop branch. There is also a cross platform Launcher available that will automatically update your build of the game so that you always have the latest version.

Some Linux distributions offer native packages already. These packages are usually third-party, but we're trying to resolve issues they are facing.

macOS:

Xcode:

The recommended way of building OpenRCT2 for macOS is with Xcode. The Xcode build will create a self-contained application bundles which include all the necessary game files and dependencies. Open the project file OpenRCT2.xcodeproj in Xcode and build from there. Building this way will handle the dependencies for you automatically. You can also invoke an Xcode build from the command line using xcodebuild.

CMake:

A command line version of OpenRCT2 can be built using CMake. This type of build requires you to provide the dependencies yourself. The supported method of doing this is with Homebrew. Once you have Homebrew installed, you can download all the required libraries with this command:

Linux:

If you are fixing a bug for the next release, please branch off and perform pull requests to the correct release branch. master only contains tagged releases, you should never branch off this.

4.1 Bug fixes

A list of bugs can be found on the issue tracker. Feel free to work on any bug and submit a pull request to the develop branch with the fix. Mentioning that you intend to fix a bug on the issue will prevent other people from trying as well.

4.2 New features
